Abstract:

This report investigates identical model small arms, in particular eight same-model pistols and seven same-model shotguns. This is an adjunct to experiments to obtain statistically significant quantities of signatures of objects of military interest. Magnetic signature features were compared to find similarities and differences between all the pistols and all the shotguns tested. In the far field region, the shapes of the component curves for each weapon were similar the relative shapes of the component signals, however, were different for both types of weapon. A comparison of total field decay with distance from pistol to sensor showed a noticeable difference when the experiment was performed indoors when compared with an open field. Finite element simulations were done to demonstrate the effect of nearby ferrous objects on the total field decay with distance.
